Ceramic powders and structures have been synthesized and manufactured by high-temperature firing. However, there are increasing expectations for the development of nanostructures that cannot be obtained by the firing method in search of higher functionality. In addition, cold crystallization is required from the viewpoints of energy saving, low environmental load, low cost, and hybridization with organic and metal materials. In this paper, I would like to introduce the development of powders and nanostructures by cold crystallization and morphological control for tin oxide, titanium dioxide, and zinc oxide. These powders and structures can be applied to various devices. A high spillover effect is expected in various fields. Furthermore, it is expected to contribute to SDGs (Sustainable Development Goals) in environmental fields such as energy saving and low environmental load.
